Best TSP Allocation and Strategy

Hello, I'm Michael Bond and welcome to our site developed for serious and reluctant TSP investors.  

I am going to walk you through the TSP funds from a different perspective than you may find anywhere else. 

I've spent years reading a lot of faulty analysis about investing in the TSP funds and the stock and bond markets in general.  Much of it comes from an academic or marketing perspective and not from basic real-world analysis. Nothing I am about to present requires a rocket scientist to understand.  

We are just going over some facts that are rarely discussed.

Part 1: Eliminating the Weaker Funds

Chasing past returns is not a good long-term strategy

Do you drive your car by looking in the rear-view mirror?  You should not invest that way either - stop looking to past returns to determine where to invest in the future.  

Look Forward

We can do a pretty good job determining the winners going forward based on what's under each fund's hood.  So let's start by eliminating the weakest funds from the mix - the TSP F and I fund.

Comparing the two low-risk funds

The TSP F fund will under-perform the TSP G fund while interest rates are rising and out perform when rates are falling. And since the TSP F fund’s yield is usually very close to the TSP G fund’s interest rate, it will match the G fund when interest rates are flat.

The difference in performance of these two funds are the capital gains or losses the F fund sustains during the year due to interest rate movements.  So unless interest rates are falling, there is no reason to be in the F fund over the G fund.  This explains why the TSP Lifecycle fund for retirees currently holds 74% G fund and only 6% F fund.

From the F fund’s inception until 2016, interest rates were declining and the F fund’s price went up due to the falling rates.  While this makes the F fund’s past performance look good when comparing it to the G fund, this has not been the case since 2016.


We are seeing downward pressure on interest rates in 2019 - a slowing global economy and a reversal by the Federal Reserve from raising rates to lowering them. This will cause a roller coaster effect on the TSP F fund while the TSP G fund price remains steady.

It is important to understand that you will often see short term bounces in the F fund when the stock market sells off.  Investors are simply running to safety and this causes a very short-term bump in the safer fixed income prices.  This does not occur for the TSP G fund because it does not hold real securities - it is a virtual fund and its interest rate is based on a formula.

When investors return to the stock market, the bump in the TSP F fund often disappears.  So for long term investors, the trend in interest rates is what matters. Last year I said the trend of declining interest rates bottomed in 2016 and was set to move higher through 2020 or at least until the next financial crisis. We are now seeing indications the financial crisis is bubbling up.

So if you expect another financial crisis, does this mean the TSP F fund will become a better performing fund. Yes, but be careful. Bond funds come with both interest rate risk and default risk, the default risk during financial crisis means you should return to the risk-free TSP G fund after interest rates bottom.

The G fund may not out-perform the F fund in 2019 if interest rates continue to pull back but it is still your best safety net.

Forget the international fund (TSP I fund)

Note: I define a "long-term investor" as someone who does NOT chase short-term movements in the market.  An investor, not a speculator.

The other fund that long term investors should avoid is TSP’s International fund.  The I fund is transitioning to broader international exposure in 2019. (Update October 2019:  It looks like someone is coming to their senses and the I fund will not have to suffer adding Chinese stocks to the fund after all - which I consider a positive. I will update this page when this policy is finalized.)

The TSP International (I) Fund will now include more emerging markets the largest being China.  It does compliment the TSP US equity funds from a geographic diversification point-of-view.  But diversification into under-performing sectors is not a benefit and remains the same with the new index it tracks.

I also expect Chinese companies to suffer under the trade war.  But the biggest problem is the lack of rigorous accounting rules and oversight in China.  Many Chinese companies will not be standing after the next bout of financial stress.  The goes for in Europe too.  

The best performing sector in world has been technology.  And guess where the world’s preeminent tech companies are listed?  They are listed in the US where their returns are captured by the SP500 index which is tracked by the TSP C fund.   

While I expect much of the froth in tech and the overall stock market to come off in 2019, once the markets reset tech should outperform once again. It is these same companies that are sitting on a lot of cash and will be able to buy other companies at bear market prices at some point in the future.

The International index (TSP I fund) is weighted with only 8% tech compared to the TSP C fund's 20% weighting.  It is those top 100 largest Nasdaq listed companies that are tracked in the SP500 index that helped the TSP C fund pull ahead of the TSP I fund.  These are the most profitable growth companies in the developed world and they sit in the TSP C fund.


The SP500 companies obtain 31% of their revenue outside the US, meaning the SP500 is already diversified internationally.  Better yet the SP500 tech sector obtains 57% of its tech revenue outside the US.  When you add the I fund to your allocations, you are quickly under-weighting the world's large tech stocks.

The TSP I fund is also holding over a 24% weighting in financial stocks and frankly Europe’s banks and finances are a bug looking for a windshield.  The European Central Banks manipulation of interest rates into negative territory merely covered up the European financial sectors and economic problems and as interest rates rise globally those issues will resurface.

If interest rates do not rise above inflation, European savers will be crushed and the demand-side of the economy will suffer. Simply put, I do not see the TSP I fund as a good long-term investment for 2019 and beyond.

While the US stock market may be more over-valued today, the global stock markets were highly correlated to the downside during the last two bear markets - meaning you can not hide in international stocks when the US stock market rolls over.

Adding emerging markets adds an additional risk to the I fund.  My additional concern on emerging markets are the lack of protections for investors in some markets which may occur during another financial crisis.

What about the Lifecycle funds?

The Lifecycle funds follow a buy and hold strategy and are simply invested in all five basic funds to include the two we think should be eliminated from the mix.  The funds are predominately invested in equities until you close in on retirement where they start shifting to the TSP G fund -- 74% in the retirement income producing fund. 

The two ovals in the next chart highlight a key point about most Lifecycle funds.  They do lose less during bear (down) markets, but the gain less during bull (up) markets. This means they are less "volatile" and this is advertised as being less risky.  With the exception of the Retirement Income Lifecycle fund you run the risk of large losses during bear markets.  You also get the under-performance of the two worst funds during bull markets.  You can do better.

TSP Lifecycle Funds

The Life cycle funds hold proportions of each equity fund (TSP C/S/I) based on their market valueWhile the equity funds are diversified geographically across the developed world based on a value weighted basis, this geographic diversification is under-weight global technology.  With the addition of emerging markets to the TSP I fund, the increased market value of this fund means the Lifecycle funds will hold a higher allocation to the I fund than before and a lower allocation of the US equity funds. 

So to keep it simple we've now narrowed our decisions down to only 3 funds to consider - the TSP C and S equity funds and the no-risk G fund...

...let's take a look at Part 2: The three best funds.

I can’t read enough!  You are saying all of the things I have been saying!  I have been successful for quite some time at stocks, but starting last December, I lost my read of the market.  Your writing is spot on and largely correct at guessing the future direction.  Love the service.  Naval aviator with an interest in finance…sounds familiar.
